这也不能解释为什么在一个由父母一方决定利手的物种中，当后代具有相同的遗传倾向时，他们并非完全是右撇子或左撇子。

Nor does it explain why, in a species where one parent determines handedness, a brood is not exclusively right or left-handed when the offspring would have the same genetic predisposition.

但是这种结合了不对称、解剖学和偶然性的进化机制并不能提供一个充分的解释来说明为什么右利手应该成为优势。

But this evolutionary mechanism combining dissymmetry, anatomy, and chance does not provide an adequate explanation of why right-handedness should have become predominant.

这也不能解释为什么在一个由父母一方决定用利手的物种中，当后代具有相同的遗传倾向时，他们并非完全是右撇子或左撇子。

Nor does it explain why, in a species where one parent determines handedness, a brood is not exclusively right-or left-handed when the offspring would have the same genetic predisposition.

Again, this is a right-handed centric thing but if you're right-handed, language on the left, math and music on the right.

重申一遍,这是以右利手为基础的研究结论,如果你是右利手,那么语言功能便定位于左半球,而数学运算与音乐则定位于右半球

And, in fact, we're going to be talking about right-handed people for the most part, making generalizations in what I'll talk about now.

实际上,我们在大多数情况下讨论到的,都是右利手的人,再从中得出我所讲的一般性结论
